FPGAs have become a competitive alternative for high performance DSP applications, previously dominated by general purpose DSP and ASIC devices. This paper describes the benefits of using an FPGA as a DSP co-processor, as well as, a stand-alone DSP engine. Two case studies, a Viterbi decoder and a 16-tap FIR filter are used to illustrate how the FPGA can radically accelerate system performance and reduce component count in a DSP application. Finally, different implementation techniques for reducing hardware requirements and increasing performance are described in detail.
